Specification of Letters Patent. 'Patentied June 13, 1911.

Application filed January v10, 1911. Serial Nb. 601,854.

To all whom it may concern:

Be it known that I, Airrium E. LAWRENCE, a citizen of the United States,.residing'at of Rays and and use- State-0t Texas, have invented new fulln'iprovemcnts in Storage Batteries, which the following is aspecification.

This invention relates to storage batteries or accumulators and theobject of the invention is the provision of a simply and cheaplyconstructed battery 0t this type which will give a comparatively highamperage for the size and number of plates used.

A further object of the invention is to provide a novel plate forstorage batteries and a novel container for the same.

Further objects of the invention will appear as the following specificdescription is read in connection with the accompanying drawing whichforms a part of this application, and in which:

plates.

Referring more particularly to the draw .ing l'represents the plate celland 2 the plate cases which ,are mounted therein and The cell comprisesthe usual glass receptacle in which the exciting liquid is held, and thecases 2 comprise a metallic receptacle having a plurality of holes lthrough which the exciting liquid is adapted to pass, and a top 5 hingedto one a knuckle joint (3. The the interior diameter of; the case andtherefore seats inside the sameon top of the plate 3. The caseand topare preferably constructed of lead and only of a sullicient width topermit the insertion of the active material of which i the plate isformed.

The positive plates are composed of one part of graphite and nine partsof litharge, while the negative plates are composed of nine parts of redcad and one part of graphite. These constituents are compoundedpreferably by weight. These PlZItQSTZIHB each pressed into form and thelead cases with suitable projections 7 on are inclosed 1n theirundersurfaces to support them above I the bottom of said cases andthereby permit a quantity of the exciting fluid to gain access to theplates. The tops 5 are secured down upon the plates by clamps 8 and theterminals of these plates may to in any suitable manner. I

Having thus described the invention, is claimed .is--

1. An accumulator plate composed of one part of graphite and nineipartsof red lead and having-a metallic covering.

A storage battery comprisi rality of negative and positive p ates, thenegative plates being composed of one part of graphite and nine parts ofred lead and the positive plates being composed of one part of graphiteand nine parts of l-itharge, and an apertured metallic covering for'saidplates. v I

3; An active platc'for storage batteries comprising a pressed body ofactive material, a metallic casing for said body, and projections onsaid body for supporting said plate above What the bottom of the casing.

be secured there- In testimony whereof I aifix my signature in presenceof two witnesses.
